Victoria Edwards, who runs the Barton Home and Office in Barton Street, sees up to 10 cars entering the one-way street.

She said: “Me and my sister have been running this shop for 20 years now and from my shop window I see cars turning into the road all the time.

“It is a big problem. I don’t think the height of the signs is a problem but they need turning at least 46 degrees outwards.

“They lowered them before and when lorries turn into the road, they twist them inwards. But it is a two-minute job for the council to come out and turn them back towards Barton Street again. Maybe if they painted ‘no entry’ on the pavement it would be better.”

Edress Onnia, who owns Blenheim Grocers, said: “The signs are too high for people to see. They need lowering.”

However, highway regulations state that signs must be at least 2.3 metres high for safety reasons.

Gloucestershire County Council highways manager Sally Godwin said: “National guidelines on traffic signs tell us to place them at least 2.3 metres high because to put them any lower could cause an injury to pedestrians or cyclists.

“We will however investigate this sign to make sure it has not been moved and is clearly visible from the road.”
